Aykroyd will be in La Mesa this weekend to promote his Crystal Head Vodka, signing the skull-shaped bottles and meeting fans.

The event is this Saturday from 11:00 a.m. to 1:00 p.m. at BevMo!, located at 8410 Center Drive in La Mesa.

"Bottles to be signed may be purchased at BevMo! prior to signing or may be brought by customer to BevMo! Dan Aykroyd may or may not sign bottles and other items presented at his discretion," BevMo!'s website states.

The vodka's website touts the product's purity. It's made with water from Newfoundland, Canada, and then it is quadruple-distilled. The pitch seems to be working: the vodka is available for sale around the world and recently won awards in Australia and San Francisco.
